Proof step 6 from proof buf-ro-rw-mode-write-lpt-other (previous step)

bleb.leb = n, lpt[bleb.leb] = mklp(m2, m3, lpf0, m4), lpt[n, lp][bleb.leb] = mklp(m, m0, lpf, m1) ⊦ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m0 = LEB_SIZE ∨ m0 = # avol[bleb.leb].data) ↔ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m3 = LEB_SIZE ∨ m3 = # avol[bleb.leb].data), bleb = buffered(n)

Proof step 7:
lpt[bleb.leb] = mklp(m2, m3, lpf0, m4) ⊦ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m0 = LEB_SIZE ∨ m0 = # avol[bleb.leb].data) ↔ bleb.isbuf? → bleb.leb < # lpt ∧ (boolvar ∧ m3 = LEB_SIZE ∨ m3 = # avol[bleb.leb].data), bleb = buffered(bleb.leb)
